The Ralph C. Wilson Jr. Foundation has made a $2.5 million grant to the Pro Football Hall of Fame in Canton, Ohio.

About $1 million of the grant will go to create an endowment to provide annual operating revenue for the Pro Football Hall of Fame.

The remaining funds will support a variety of programs and projects, including a holographic theater experience focused on the values learned from the game and digitization of the Hall of Fame archives to create a comprehensive digital archive for every NFL player past and present.

Mary Owen, executive vice president of the foundation, a member of the Hall of Fame’s advisory committee and the niece of the late Ralph Wilson Jr. announced the gift Wednesday at the Ohio museum.

The foundation’s grant builds on a $2.5 million gift Wilson made to the Hall of Fame in 2012. That gift funded The Ralph Wilson Jr. Pro Football Research & Preservation Center, a state-of-the-art archive that is home to more than 30 million pages of documents and 5 million photographic images.

Wilson was one of the original founders and a guiding force of the American Football League. He guided the Bills franchise from the team’s inaugural 1960 season through his death in March 2014. He was elected to the Pro Football Hall of Fame in 2009.

The Grosse Pointe Farms-based foundation, funded late in 2014 with a $1.2 billion bequest from Wilson’s estate, last year said it planned to make $60 million in legacy grants to nonprofits he had supported during his lifetime during its first year before moving to a long-term grant cycle/funding process this year.
